Well ideally we would want to use the Samsung 830 SSD.
Like I said it's all about balancing the budget. The cheap £10 keyboard and mouse set isn't a bad idea either as these can be upgraded cheaply enough over time.
The i5K has £20ish off whilst on offer, which in my eyes helps pay for the achilles HS to overclock it. Deals change tomoz so makes sense not to hang around too long arguing what's best. I think the OP can balance something nice for the cash with all the info we've given him
